Abstract: |
In view to the concentrate grade is difficult to improve due to the gangue minerals of a tungsten-copper mine are mainly pyrrhotite, silicon-bearing minerals and fluorite, a flowsheet consisting of Cu-S bulk flotation and Cu/S separation was adopted combined with some effective reagents. From the raw ore containing 0.382% Cu and 12.33 g/t Ag, a silver-bearing copper concentrate assaying 21.75% Cu at 89.39% recovery and 442.35 g/t Ag at 56.33% recovery was obtained. In addition, a flowsheet consisting of magnetic separation discarding tailings, room temperature tungsten roughing and heated tungsten cleaning was adopted combined the effective tungsten collector GY-10. From the raw ore containing 0.181% WO3, a tungsten concentrate assaying 62.04% WO3 at 71.98% recovery was obtained, which realized the comprehensive utilization of tungsten-copper polymetallic ore resources. |
